Abstract (en)

[origin: WO9323968A1] An electric heating device (34) in which is included an electric energy source (45) which is designed as a thin film battery (45). The heating device also includes a resistor heating unit (40) comprising a first material stratum (40) consisting of an electrically conductive polymer material with PTC properties. The resitor heating unit (40) and the electric energy source (45) are disposed adjacent one another and form a composite unit in which the major surfaces of said first material stratum (40) and thin film battery (45), respectively, face towards one another. Electrodes (41, 43) are connected, by the intermediary of a switch (48), to the poles of the battery (45) and to the resistor heating unit (40).
